Introduction
In recent years, the sale of bump stocks has become a contentious issue in the United States. Bump stocks are devices that can be attached to semi-automatic firearms, allowing the shooter to fire the gun at a rate similar to that of an automatic weapon. Despite being banned in several states, the question of how many bump stocks have been sold in the US remains a topic of debate. This article delves into the available data and provides a comprehensive analysis of the situation.
The Controversy Surrounding Bump Stocks
Bump stocks gained notoriety following the tragic shooting at the Las Vegas Route 91 Harvest Festival in 2017. The attacker used a bump stock-equipped firearm to fire numerous rounds in a matter of seconds, resulting in the deaths of 58 people and hundreds of injuries. This incident sparked a national debate on gun control and the legality of bump stocks.

In response, several states have implemented bans on bump stocks, while the federal government has also taken action. In March 2019, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) classified bump stocks as machine guns, effectively making them illegal under federal law.
Determining the Number of Bump Stocks Sold
However, determining the exact number of bump stocks sold in the US remains a challenge. The ATF does not track the sale of bump stocks, and manufacturers have not been required to report sales to the government. As a result, estimates of the number of bump stocks in circulation vary widely.
One study conducted by the Crime Prevention Research Center (CPRC) in 2018 estimated that between 500,000 and 1 million bump stocks were sold in the US before they were banned. The study's author, John R. Lott Jr., cautioned that these numbers are only estimates and that the actual number could be higher.
State-Level Banning Efforts
The implementation of state-level bans on bump stocks has also contributed to the difficulty of determining the number of bump stocks sold. For example, California banned bump stocks in 2018, but it is unclear how many bump stocks were in circulation before the ban took effect. Similarly, other states with bans may have had varying degrees of success in removing bump stocks from the market.
Conclusion
While it is difficult to determine the exact number of bump stocks sold in the US, it is clear that these devices have the potential to significantly increase the lethality of firearms. The banning of bump stocks at both the state and federal levels is a step in the right direction, but more research and data collection are needed to fully understand the scope of the issue. As the debate over gun control continues, it is crucial to consider the potential impact of accessories like bump stocks on public safety.
